There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a non-interventional prospective, comparative study of white-to-white, corneal thickness, and anterior chamber depth measurements as taken on the Orbscan II compared to the IOL Master 700 (Zeiss), IOL Master 500 (Zeiss), Atlas 9000 (Zeiss), Lenstar 900 (Haag-Streit), Argos (Alcon), iTrace (Tracey), Pentacam (Oculus), and manual calipers.
The overall goal of this research is to better understand if and how the Elders' Resilience Curriculum (ERC), a culturally grounded, school-based upstream suicide prevention program taught by White Mountain Apache Tribe (WMAT) Elders to youth, promotes connectedness, cultural strengths, and reasons for living among American Indian youth.
The purpose of this pilot randomized controlled trial is to investigate the effects of aromatherapy on postoperative anxiety and pain in total knee replacement patients. The main questions to answer are: Does Lavender-Peppermint Aromatherapy reduce post operative anxiety in patients after primary total knee replacement when compared to placebo? Does Lavender-Peppermint Aromatherapy reduce post operative pain in patient after primary total knee replacement when compared to placebo? Does Lavender-Peppermint Aromatherapy reduce postoperative opioid consumption after primary total knee replacement when compared to placebo? Does Lavender-Peppermint Aromatherapy reduce postoperative nausea and vomiting after primary total knee replacement when compared to placebo? Participants will be assigned to one of the following groups at random: - Intervention: Aromatherapy with the lavender-peppermint scent - Control: Aromatherapy with the almond oil scent Participants will also be asked to complete pre- and post-operative questionnaires. Researchers will compare both groups (intervention vs control) to see if aromatherapy reduces post-operative anxiety, pain, opioid intake, and nausea/vomiting.
This study will evaluate the impact of long-term use of a desensitizing toothpaste containing 0.454 percent (%) stannous fluoride (SnF2) on oral health related quality of life (OHrQoL) in a population of self-reported dentin hypersensitivity (DH) sufferers. Data generated will provide real world information on the DH experience and DH management with a daily use anti-sensitivity treatment.
The purpose of this study is to assess the clinical performance of DAILIES TOTAL1® spherical soft contact lenses over approximately 1 week of daily wear.
The primary objective of this study is to analyze smart phone-based Transdermal Optical Imaging (TOI) features to develop a model that can discern hypohydration from euhydration status including 1) a small feasibility study for 24-hour data collection in the general population using passive dehydration or ad libitum fluid intake (GENPOP), 2) an exercise study in moderately active participants in both dehydrated and euhydrated states (EXERCISE). TOI data will be collected alongside standard reference measures of hydration status. This is an exploratory pilot proof of concept study with each subject serving as their own control.
Motivational deficits such as anhedonia are core to several psychiatric disorders and underlie significant functional impairment. This double-blind, placebo-controlled crossover trial of minocycline, an anti-[neuro]inflammatory agent, examines links between chronic stress and responses to a reward-related motivation task. It will evaluate the effects of pharmacologically attenuating neuroinflammation on behavioral responses to a reward-related motivation task in individuals experiencing unemployment. Understanding the effects of neuroinflammation on reward function among individuals experiencing chronic stress represents a critical first step in identifying novel neuroimmune targets for future clinical trials.
A child's ability to effectively communicate with peers, parents, and caregivers impacts their level of independence and quality of personal relationships. This retrospective study will compare the speech development of participants aged 2 - 17 years that received 40 sessions of HBOT at 2.0 ATA to those who had not. Both groups will have a verbal assessment every six months. There were 32 subjects in the HBO group and 33 subjects in the non-HBO group. The statistical analysis will focus on whether Hyperbaric Oxygen Therapy made a significant difference in Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) or Assessment of Basic Language and Learning Skills (ABLLS) results.
Venous thromboembolism is prevalent, associated with a high degree of morbidity and mortality, and largely preventable. External mechanical compression is a standard of care for prevention, but compliance with traditional external mechanical compression devices is low due to patient reported issues with comfort, mobility, usability, noise, and sleep disturbances. The purpose of this study was to compare user-rated comfort, mobility, usability, noise, perceived sleep disturbance, and objective sleep disturbance for a novel external lower limb mechanical compression device as compared to a standard sequential compression device. Using a 2-day counterbalanced, within-subject repeated-measures design, 16 participants wore two mechanical compression devices, the commonly-used Kendall sequential compression device Express 9525 and the novel Recovery Force Movement and Compressions Device for 1 night each in their home while sleep was recorded with polysomnography. For each device, participants also completed questionnaires to assess usability, mobility, perceived noise disturbance, and perceived sleep disturbance.
The objective of this research is to demonstrate superior anti-inflammatory effects, as demonstrated by a reduction in TNF-a and IL-17A, with tazarotene/halobetasol lotion in patients with mild to moderate plaque type psoriasis as compared to clobetasol propionate 0.05% cream.
